To @ZZ whom it may concern:

Beit known that I, ANTON CLIFFORD, a citizen of the UnitedStates,residing at Winnetka, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Sash-Locks, of which thefollowing is a specification.

This invention relates to locks for windowsash, and has for its objectthe production of an improved lock having a pivoted bolt intended tooverlie the lower sash and to enter a keeper in the upper sash, whichbolt auto# matically folds upward when withdrawn from said keeper andwhen the lower sash is raised.

In the accompanying drawings, Figure lis a perspective View of thisimproved sash-lock detached from a window. Fig. 2 is a view showing it-applied to* a window-casing and in a position to lock both of the sash.Fig. 3 is a view similar to the preceding figure, excepting that thelocking-bolt is represented as withdrawn from the keeper. Fig. 4 is aView showing the lower sash raised, illustrating the position which thelocking-bolt then assumes; and Fig. 5 is a plan view of the lock, itsparts being in the positions indicated in Fig. 2.

Like letters of reference indicate corresponding parts throughout theseveral views.

In the construction of this sash-lock I provide the attachingplate A,having the diagonal loop A formed integral therewith and rising abovethe face of said attaching-plate. A2 shows countersunk openings formedin the face of said attaching-plate for receiving screws A?, by means ofwhich said plate is secured te the window-casing. A pivotal screw Bextends through an opening in said loop A' and said plate A, enteringthe woodwork of the window-casing, to which the plate A is secured.

C is a locking-boltadapted to lie within the loop A', having thelongitudinally-elongated opening C', by means of which said bolt ismounted upon the pivotal screw B. The bolt C thus is capable of asliding movement with relation to said plate A, limited by the length ofthe elongated opening C. A gravity-latch C2 is pivotally mounted uponthe screw B and is adapted, to engage a shoulder O3 at the rear end ofthe locking-bolt C, its purpose being to prevent the Withdrawal of saidbolt from its keeper, to be later described.

C4 is a knob fixed to the bolt C, by means of4 which said bolt isoperated.

D is a keeper-plate having the keeper-opening D' and the countersunkopening D2 for receiving an attaching means by which said keeper-plateis secured to the upper sash of the window. V

E is the window-casing, F the upper sash, G the lower sash, and G thesash-cord, all arranged in the usual manner.

The application of lthis sash-lock to a win-v dow is as follows: Thelower sash is lowered,

and the upper sash raised as far as possible. The attaching-plate A issecured'to the Window-casing in such position that the lockingv bolt Cwill rest firmly upon the top of the lower sash. The keeper-plate issecured to the upper sash in such position that the bolt when thrustforward will enter the keeperopening D@ Then the bolt is thus thrustforward, the sash of the window will belocked in a closed position. Tounlock them, the gravity-latch Cgis raised from its engagement with theshoulder Gilat the rear of the lecking-bolt C and said bolt withdrawnfrom the keeper-opening D. The lower sash may then be raised and thelocking-bolt C will assume the position indicated in Fig. 4, or theupper sash may be lowered and the bolt will remain in the positionindicated in Fig. 3.

The length of the bolt C is'made to `correspond to the thickness of thewindow-sashthat is to say, it may be made `longer for thicker sash andshorter for thinner ones.

I claim as my invention* 1. In a sash-lock, in combination, anattaching-plate having a standing loop; a locking-bolt having a pivotaland a sliding connection within said loop, which bolt is adapted to lieupon the top of the lower sash and to enter a keeper-opening in theupper sash; and a keeper plate having a keeper-opening therein.

2. In a sash-lock, in combination, an attaching-plate having a diagonalstanding loop; a locking-bolt having an elongated opening, a pivot forsaid bolt, extending through the elongated opening therein, and adaptedto be supported on said loop and the attach ing-plate; a keeper-platehaving a keeperopening for receiving said locking-holt; and means VforSecuring the attaching-plate to the window-casing.

3. In asash-lock, in combination, alockingbolt having an elongatedopening therein; an attaching plate having a pivot extending through theelongated opening in said bolt;

a latch adapted to engage a notch in said bolt i a keeper-plate having akeeper-openin g therein and separate means for securingthe-attaching-plate to the Window-casing, and the keeper-plate toone ofthe WindoWsash.

4. In a sash-lock, in combination, aloekingv bolt having a longitudinally-elongated open- 15 ing therein; an attaching-,plate having astanding loop; a pivot on said attaching-plate extending through saidelongated opening; a latch adapted to engage a notch in said bolt; akeeper-plate having a keeper-opening therein; and separate means forsecuring the attaching-plate to the window-acasing, and the keeper-plateto one of the Window-sash.
